    runtime: fix syscall error returns on mips/mips64/ppc64 · acd30e9a
    David Wimmer authored
    The linux syscall functions used in runtime are designed around the calling
    convention of returning errors as negative numbers. On some other systems
    (like mips and ppc) the actual syscalls signal errors in other ways. This
    means that the assembly implementations of the syscall functions on these
    platforms need to transform the return values in the error cases to match
    the expected negative errno values. This was addressed for certain syscalls
    in https://golang.org/cl/19455 and https://golang.org/cl/89235. This patch
    handles the rest of the syscall functions in sys_linux_*.s that return any
    value for mips/mips64/ppc64.
    
    Fixes #23446
